As the title suggests. On the Developer Tools CD that came with my mac I had XCode 3. With the new download, will it come with these developer tools and if so will it be XCode4? I use the free XCode v3/iOS SDK but if I updated to Lion will XCode 4 be installed? If it is and I use the free version of the SDK will that overwrite XCode 4 with XCode 3 or will the release of iOS5 come with XCode4? Make sense!?
